IGBT Transistor Brand Story

“IGBT (Insulated Gate Bipolar Transistor)” – green represents human wisdom and love for nature

This color represents the spark and passion of human wisdom, and also triggers our deep thinking about environmental protection and new energy. As a key power electronic device, its invention and development have changed the world of industrial automation. It makes current and voltage control more precise and promotes the advancement of green energy technology, thus providing support for the sustainability of nature.

“TRANSISTOR” – white symbolizes pure and fertile land
It represents the integration of technology and nature. Just as the land breeds all things, transistors, as one of the core components of electronic equipment, also carry the “nutrients” of global scientific and technological progress. Transistors are the cornerstone of the modern electronics world, driving developments in everything from communications to computing, from energy to digital energy. Just as fertile soil provides the soil for plants to grow, transistors power all types of electronics and make countless innovations a reality.
